Please note: the results below are estimates based on current (limited) understanding of the impact process and come with large uncertainties; they should be used with caution, particularly in the case of peculiar input parameters. All values are given to three significant figures but this does not reflect the precision of the estimate. For more information about the uncertainty associated with our calculations and a full discussion of this program, please refer to this article

Your Inputs:
- Distance from Impact: 10.00 km ( = 6.21 miles )
- Projectile diameter: 1000.00 km ( = 621.00 miles )
- Projectile Density: 8000 kg/m3
- Impact Velocity: 60.00 km per second ( = 37.30 miles per second )
- Impact Angle: 90 degrees
- Target Density: 2500 kg/m3
- Target Type: Sedimentary Rock
-
Energy:
- Energy before atmospheric entry: 7.54 x 1030 Joules = 1.80 x 1015 MegaTons TNT
- The average interval between impacts of this size is longer than the Earth's age.
- Such impacts could only occur during the accumulation of the Earth, between 4.5 and 4 billion years ago.
-
Major Global Changes:
- The Earth is not strongly disturbed by the impact and loses negligible mass.
- 6.10 percent of the Earth is melted
- The impact does not make a noticeable change in the tilt of Earth's axis (< 5 hundreths of a degree).
- Depending on the direction and location of impact, the collision may cause a change in the length of the day of up to 26 milliseconds.
- The impact does not shift the Earth's orbit noticeably.
-
Crater Dimensions:
- What does this mean?
- Transient Crater Diameter:
6280 km ( = 3900 miles )
- Transient Crater Depth: 2220 km ( = 1380 miles )
- Final Crater Diameter:
19700 km ( = 12200 miles )
- Final Crater Depth: 5.8 km ( = 3.6 miles )
- The final crater is replaced by a large, circular melt province.
- The volume of the target melted or vaporized is 6.71e+10 km3 = 1.61e+10 miles3
- Melt volume = 2.07 times the crater volume
- At this size, the crater forms in its own melt pool.
-
Ejecta:
- What does this mean?
- Your position was inside the transient crater and ejected upon impact
